WebMar 31, 2024 · The IEEE Spanning Tree Protocol (STP) was developed to provide a standard way of creating a loop-free topology for Ethernet networks. Before STP was published, many vendors who sold VLAN-capable switches developed versions of STP that were compatible with their products. WebSpanning tree protocol (STP) identifies links in the network and shuts down redundant links, preventing possible network loops and broadcast radiation on a bridged network. STP also provides redundant links for automatic failover when an active link fails.
